I'm not calling shenanigans, but...I haven't seen any of these around, and I spend a lot of time in WSO. Should I call that number and volunteer my services? Assuming the article's legit and not just a puff piece, this sounds like a project that sudo should be working with.

Even if it's BS, I recall someone- quite possibly from sudo- mentioning a bike trailer/Conestoga wagon type thing that sounded pretty cool. I don't remember whether they built it or were planning to build it...anyone?
